Abstract: Disclosed is a multi-view three-dimensional (3D) image display apparatus using a modified common viewing zone. The multi-view 3D image display apparatus may use a modified common viewing zone between a central viewing zone (common viewing zone) of the multi-view 3D image display apparatus and a central viewing zone (parallel viewing zone) of a 3D image display apparatus employing an integral photography method, or form a common viewing zone at an optimum viewing distance (OVD) of the multi-view 3D image display apparatus and use a modified common viewing zone in an area beyond the OVD.

Abstract: Disclosed are a system and method for measuring viewing zone characteristics of an autostereoscopic three-dimensional (3D) image display device. The system for measuring viewing zone characteristics of the autostereoscopic 3D image display device includes at least one image sensor that is provided on a front side of the image display device, and measures characteristics of luminance distribution of viewpoint images in a depth direction (Z-direction) formed from at least two local areas which are designated in advance in a horizontal direction (X-direction) of the image display device, and a determination unit that determines, as an optimum viewing distance (OVD), a position of the image sensor corresponding to a depth direction (Z-direction) having a horizontal direction (X-direction) minimum deviation of a center position of luminance distribution of light generated from the same viewpoint image of each of the at least two local areas by analyzing the characteristics of luminance distribution on an X-Z plane measured from the image sensor.

Abstract: Provided is a three-dimensional (3D) image display apparatus using laser beam scanning (LBS) projection optical systems. The 3D image display apparatus includes a plurality of LBS projection optical systems arrayed in horizontal and vertical directions, an input unit through which a 3D image signal is input, and an image signal controller configured to distribute the 3D image signal input through the input unit to the LBS projection optical systems. Each of the arrayed LBS projection optical systems has a beam-projection center point for outputting light to an outside of the LBS projection optical system, and an image projected from the beam-projection center point is a horizontal-parallax image based on the beam-projection center point.

Abstract: The present disclosure relates to a 3-dimensional displaying apparatus using line light sources, which includes: a display panel having a plurality of pixels; a backlight panel having a plurality of line light sources disposed to be spaced apart from each other by a predetermined distance, the backlight panel being spaced apart from one surface of the display panel; and a distance-adjusting unit for adjusting a distance between the backlight unit and the display panel. According to the present disclosure, it is possible to display autostereoscopic images which may minimize the quality deterioration of the 3-dimensional images according to the change of distance from an observer to the 3-dimensional displaying apparatus, which is a problem of a displaying apparatus implementing 3-dimensional images by using a general parallax separating unit.
